The usb audio cable is an original replacement connection lead engineered for charging and transferring audio files from selected covert voice recorders to a computer.
Replacement Connection and Charging Lead
Many covert listening products feature a discreet 2.5mm 4-pole jack port instead of a conventional USB socket to preserve stealth and maintain compact housing dimensions.
This original component usb audio cable connects seamlessly between your recorder’s jack port and a standard USB socket on any Windows PC or Mac laptop.
Connecting the lead allows you to rapidly offload recorded audio evidence, review voice files via media player software, and recharge the recorder’s internal battery in a single operation.
Whether replacing a lost original lead or keeping a spare in your toolkit, it provides essential connectivity for your covert recorder accessories collection.
Compatible Products Across Our Range
Specifically built to handle signal routing for 2.5mm 4-pole devices, this usb audio cable is compatible with older versions of the Enduro Black Box Recorder, Air Freshener Voice Activated Recorder, Carbon Monoxide Alarm Recorder, Executive Voice Recorder Spy Pen, older Smoke Alarm Recorder models, and the Spy Pen Digital Recorder (Voice Activated).
Please note that several newer voice recorders in our catalog now utilize magnetic charging connections. If your device uses a magnetic connection lead, you will require our Magnetic Audio Cable instead.
Provided you deploy your surveillance equipment for lawful purposes, the situations that suit using a voice recording device with direct lead extraction are extensive.
